method and apparatus for removing iodine
from a nuclear reactor coolant

ABSTRACT

A METHOD AND APPARATUS FOR REMOVING IODINE-131 AND IODINE-125 FROM A LIQUID SODIUM REACTOR COOLANT. NONRADIOCATIVE IODINE IS DISSSOLVED IN HOT LIQUID SODIUM TO INCREASE THE TOTAL IODINE CONCENTRATION. SUBSEQUENT PRECIPITATION OF THE IODINE IN A COLD TRAP REMOVES BOTH THE RADIOACTIVE IODINE ISOTOPES AS WELL AS THE NON-RADIOACTIVE IODINE.

Cl. 176-37 1 Sheet Drawing. 14 Pages Specification A method and apparatus for removing iodine-131 and iodine-125 from a liquid sodium reactor coolant. Nonradioactive iodine is dissolved in hot liquid sodium to increase the total iodine concentration. Subsequent precip itation of the iodine in a cold trap removes both the radioactive iodine isotopes as well as the non-radioactive iodine.
